What Social Network Analysis software do you use?

12.05.2010

See a the poll here by Gabriel Rossman at Code and Culture. I voted for R and ‘igraph’. If you use R you are getting access to all the other wonderful things that come with R. Using specialized package, like Pajek, UCINET etc requires constant going back and forth between network software and some other general analytical software (sas, spss,...

Social contagion? Maybe not…

28.07.2010

Recently there was a lot of racket about results presented in papers by a pair Nicholas Christakis & James Fowler. Their papers gained a lot of attention both in the academic world as well as in media. In their papers they claim to provide evidence for social contagion (transmission through social networks) of several types of individual characte...

From igraph to network and back again

25.08.2010

The Hobbit, or There and Back Again (by Alan Lee) In an effort to achieve this (last paragraph), I created a couple of functions to coerce networks as ‘igraph’ objects to networks as ‘network’ objects and vice versa. I wrapped them into a package called ‘intergraph’ which I just uploaded to my personal miniCRAN. Please mind, this is s...

Namespaces and name conflicts

31.08.2010

R packages ‘igraph’ and ‘network’ are good examples of two R packages providing similar but complementary functionalities for which there are a lot of name conflicts. As for now the ‘igraph’ package has a namespace while the ‘network’ package (version 1.4-1) does not. This became an issue when I was working on the ‘intergraph‘...

Installing ‘intergraph’ package

17.09.2010

After some e-mails I decided to put together a bit more detailed instruction how to install the ‘intergraph’ package together with the namespaced version of the ‘network’ package. See here. There seemed to be some problems with downloading the namespaced ‘network’ from my webstite (thanks Neil!). File permissions were set incorrectly....

intergraph+network: no hacking necessary

02.11.2010

A short update on network+intergraph R packages story: Couple of days ago Carter Butts released a new version of the ‘network’ package (ver. 1.5-1). It has a namespace now. Consequently, the ‘intergraph’ package should work out-of-the-box. There is no need to install my hacked version of the ‘network’ package anymore. Related To lea...

R with Vim

02.12.2010

For all those who think that Vim is The Editor for text files, and simultaneously think that R is The EnvironmentForStatisticalAnalysisAndGraphics. After trying out various options for intergrating Vim with R I settled on the following configuration: Use Vim-R-pluginfor editing R code files, R documentation files (*.Rd) as well as the Sweave fil...

R Studio

R Studio on MS Windows If you think that R is The EnvironmentForStatisticalAnalysisAndGraphics but you do not think that Vim is The Editor for text files you might want to have a look at R Studio. It works on Windows, MacOS and Linux. I tried it out on my Ubuntu and it looks and works brilliantly. See more screenshots here. I will seriously co...

Shortest paths to/from nodes of a certain type

14.09.2011

Elijah asked the following via SOCNET mailing list: I was wondering if anyone knew of a script or tool which would give me the network distance of nodes to a particular class of nodes.  I think of this as an Erdos number, except instead of getting the distance to one node, I want the distance to the closest node of a particular class.  Let’s ...
